Application filed February 10, 1922. Serial No. 535,505.

To all 'whom t may concern Be it knownthat I, PATRICK J. LUCEY, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have yinvented certain new and useful-Improvements in Adjusting Means for Slicing-Machine Knives, of which the following is a specification.

My invention relates to new and useful improvements in adjusting means for slicing' machine knives, and has for its main object the pro-vision of means for conveniently and accurately adjusting the slicing machine knife axially on the machine and in exact position with respect tothe machine table.

Another object of the invention is to provide means on the machine, and particularly on the machine bracket which supports the bushing carrying the knife, to ybe readily operable by hand for conveniently releasing said bracket to permit adjustment of said knife bushing in said bracket, and for readily locking said bracket on said bushing,

And another object is to provide means for accurately adjusting the knife and its carrying means axially, and means conveniently operable lfor fastening the knife carrying means in its adjusted position and for the releam'ng said knife carrying means.

In the slicing machines with circular knives, which are now on the market, the knife is mounted to rotate on a bracket, usually by fastening' the knife to a shaft which rotates in. a bushing, and the bushing with the knife being slidable in the bracket longitudinally of the bushing and axiallyy of the knife. The bracket is usually cylindrical in form and clasps the bushing, be` ing opened along the cylindrical wall and provided with extending lips (see Fig. l) which are drawn together by means of one or morey bolts fastened thro-ugh said lips in order to clamp and retain the bushing in position in the bracket. To fasten or-loosen the nuts on the bolts a wrench is required which is not always at hand; and as the knife, which is circular inform, becomes worn down, it becomes smaller in diameter and its effective cutting edge thereby gradually recedes from the machine table. jIn order to adjust the knife in proper position with respect to the table, it has heretofore been necessary to find a wrench and release thebolts which hold the lips of the bracket together, and then it has been the practice to hit the bushing at the outer end with such wrench or a similar article, in order to drive the knife into its proper posi-k tion adjacent the machine table, and as the blows usually drove the knife too far the knife end of the bushing had to be hams mered to drive the bushing backward. This is at best a tedious and inaccurate manner of adjusting the knife laxially into its correct position with respect to the machine table;A and toI my knowledge no especial means have heretofore been provided 'on the slicing machine for accurately and readily adjusting thev knife axially intowitsI proper position with respect to the table. It is my object to overcome the above defects and to provide means for accurately and conveniently adjusting the knife with respect to the machine table and also to provide means which are conveniently operable for lock-l ing said knife and its bearing in such ad-l justed position.

Other objects will appear hereinafter. 'Ihe invention consists in the combinations and arrangements of parts hereinafter described and claimed. n

'Ihe invention will be -best understood by reference to the accompanying drawings forming a part of this specification, and in which,

Fig. l is an end elevation of my improved adjustable mounting lmeans for the knife;

Fig. 2 is a vertical sectional view, taken on line 2-2 of Fig. l, looking in the direction of the arrows; l 'v f Fig. 3 is an enlarged sijde elevational view, looking ina directionopposite tothe arrowsinFigl,v

\ Fig. i is an enlarged yfragmentary sectional view, taken on line 44 of Fig. 3, and *"5 Fig. 5 is an enlarged fragmentary sectional view, taken ony line 5-5 of Fig. 1. y

In the drawing,I have shown a portion of the frame l() of a slicing machine of well known construction, provided with a table ll slidab-ly mounted on said frame, as by means of arms 12 depending from said table,

and slidably engaging the horizontal shaft 13 supported on uprights la on the frame. In this form of construction the chain housing 16 on the frame is provided at its upper end with a cylindrical bracket or supporting member 17, and a lip 1S is provided on each side of a longitudinal opening in the wall of said bracket.

The circular and spherical or dished knife 2O is rotatably mounted on said bracket 17, usually by means of a knife shaft 2l which is fixed to the knife and is rotatably mounted on the ball bearings in a bushing 22 adjustably mounted in said bracket 17, said shaft 2l being held against axial movement in said bushing by a pair of washers and lock-nuts, and a chain wheel 2e engaged by the drive chain 25. rl`he parts above described are sul stantially the same as those found in the slicing machines now on the market.

li/ly improved and conveniently operable means for accurately adjusting the knife and supporting; bushingI axially in the bracket and in correct position with respect to the machine table, comprises a Afarmed or double yoke-shaped member 27 fastened to the bushing 22 and extending outward, away from the shaft and lock nuts, and a til-shaped strap or member 28 fastened to the bracket 17, outward of member 27.v e. shaft 29 has threaded engagement in member 28 and rotatable engagement with member 27 by means of a flange 30 on said shaftv 29 and a washer 31 fastened to the end of said shaft by means of a bolt 32 and a retaining pin 33 which passes through the head of the bolt and the washer 31 and into the shaft. A hand wheel 34, is provided on the outer end of shaft 29.

My conveniently operable means for drawing the lips 18 of the bracket together and thereby clamping the bushing 22 in position in said bracket, comprises a lever 36 pivoted with one end. to one of the lips and having a curved. slot 37 which engages a pin 88 on the other lip. A bolt 39 is slidably mounted in a slot a() opening toward the forward part of one lip (see Figs. and a) and is actuated by a head al and a stem Lil-2 which is connected to said bolt and is slidable in a slot 4 3 on the side of said lip (see Fig. l). A spring la is placed in the inner part of slot a0 to force the bolt 39 outward and a notch may be cut on the upper and lower side of lever 36 where said bolt engages said lever. This bolt thus provides means for retaining the lever in either its position to lock the bushing or to release the bushing in the bracket.

While 1 have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departfrom the spirit of the invention. l, therefore, do not wish to b e limited to the precise details of the construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.
